Please help with step by step instructions

Step-by-step explanation:

This is classic right triangle trig.  Let's identify the sides in this triangle according to the values they have been given.  The longest side and the side across from the right angle is always the hypotenuse, so the hypotenuse measures 12.  The side measuring 5 then is adjacent to the angle x.  The side across from it is one we do not need to know (but could solve for if we had to using Pythagorean's Theorem!).  The trig ratio that relates an angle to its hypotenuse and adjacent side is the cosine of the angle:

In order to find a missing angle on your calculator, you'll use the 2nd button and the cos button.  On your screen you'll see this:

 and after the parenthesis, enter in 5/12 and hit "enter" to get the angle.  It's 65.4 degrees.  If you didn't get that, check your calculator to make sure you're not in radian mode!!!

answer: 2 litters juice bottle

half of a gallon is 50% of a full gallon 2 litters of juice is 52% of a full gallon

hope this ^_^

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
